Speaking of Pound Cake & Weights
That is how the thing got it's name.
Original recipes for pound cakes called for flour, eggs, butter, and milk in measures of "pounds" depending upon size and or number being made.
Regarding standard weights:
Current American usage give eight ounces for a cup, two cups to a pint and four quarts makes a gallon. One pint of water weighs one pound.
However for the UK twenty fluid counces made an imperial pint, therefore the Imperial gallon was 25% larger than an American one.
But in the British empire, it took 20 (fluid) ounces to make an imperial pint, making the Imperial gallon 25% bigger than the American gallon.
Hence the common American claim that "a pint is a pound the world around" pitted against the English statement that "a pint of water weighs a pound and a quarter".
, 8 ounces make a cup, 2 cups make a pint, two pints make a quart, 4 quarts make a gallon. A pint of water weighs a pound.
